WOVEN CARTRIDGE-BELT.

SPECIFICATION forming part of Letters Patent No. 507,836, dated October 31, 1893.

7 Application filed May 20,1893.

To all whom it may concern;

Be it known that I, THOMAS C. ORNDOBFF, of the city and county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Woven Cartridge- Belts, of which the following is a specification.

My invention has relation to a cartridgebelt made of woven material having the body of the belt, and the cartridge thimbles or pockets woven in one piece, and in one and the same loom. A belt of this kind broadly considered is not new; it is described in Millss patent, No. 193,613, of July3l, 1877, and

December 28, 1880in which latter patent the belt is composed of a double fabric woven on one thickness of the fabric with thimbles or pockets which extend only part way across the fabric leaving at each edge a selvage com posed of the full thickness of the fabric.

It is my object to double the cartridge carrying capacity of the belt, without materially increasing its bulk or weight.

To this end my'invent-ion,generally speaking', consists in providing the belt with a second layer of pockets or thimbles exterior to the first layer, both layers being integral or woven in one with the body of the belt. In the preferred embodiment of my invention the pockets of this second layer alternate with those of the first, and are carried by and formed in the outer extremity of woven double ply tongues which project outwardly between the pockets of the inner layer just far enough to permit the outer pockets to seat themselves betweenthe diverging convex outer portions of the Walls of the main pockets.

The nature of my invention and the manner in which the same is or may be carried into effect will be understood by reference to the accompanying drawings in which- Figure l is a perspective View of a belt embodying my improvement in its preferred form. Fig. 2 is a diagram representing a part of the belt in longitudinal section and on greatly enlarged scale, in order to indicate the warp, weft and binders in their relative positions in'the belt and the two series of pockets. Fig. 3 is a diagrammatic view similar to Fig. 2 of a modification.

The belt which I have selected to illustrate my invention, is, with the exception of the Serial No, 474,942. (ModeL) The two thicknesses of fabric which compose the belt are shown in Fig. 2. The warp threads of the inner thickness are marked a; the weft threads of that thickness are marked 12. The warp threads of the outer ply or thickness are marked 0; the weft threads of that thickness are marked (1. The two series of binders which hold together the two thicknesses and cause them to form one fabric are marked e, f. The thimbles or pockets 0 extend only part way across the belt leaving at edge a selvage composed of the full thickness of the double fabric; they are formed of the warp and weft c d of the outer ply. The warp and weft of the inner ply do not enter into the composition of the thimbles.

Thus far there is nothing new in the belt, it being substantially the same as that described and claimed in Patent No. 236,059, last above referred to.

I pass now to a description of my improvement. The preferred embodiment of the invention is shown in Figs. 1 and 2, and contemplates the addition to the belt of pockets D which alternate with the pockets 0 and form a layer of pockets exterior to the first layer 0. In the belt shown in these figures, each pocket D is woven in one with and is carried by a double or two ply tongue E of fabric which is in one with the outer ply of the belt, and extends out between contiguous pockets 0 of the inner layer. This result is produced by means of the binders f, which in the weaving are carried into the, fabric of which the two plies of the tonguesE are com-' posed. The binders f are carried by a separate warp beam from the binders e. Usually in the weave I have twelve binders e and twenty-four binders f, each set of binders having its own separate warp beam and harness. Neither set enters the fabric of the pockets C; both enter the fabric of the body of the belt; and the bindersfalone enter the fabric of which the tongues E are composed but are omitted from the outer pockets D. Thus during the weaving of the pockets 0, both sets of binders are thrown out of the weaving. When however the tongues E are being woven, the binders c are thrown out of the weaving, but the binders f continuein until the fabric composing the first ply of any one tongue is completed; then they are thrown out of the weaving (at the point 2' while the fabric of the pocket D is being woven; and then when this last named fabric has been woven of the proper length for the pocket, the binders are again brought with the weaving thus uniting the ends of the pocket fabric at the pointt'; and they continue in the weave of the second ply of the tongue E, until that has been completed, when the binders e are also thrown in and the weaving of the body of the belt proceeds. It probably will have occurred by this time to the reader that inasmuch as the tonguesE are composed of two pliesjoined only at their outer and inner ends, they are in eifect tubes which might serve as the inner layer of thimbles or pockets. Such a construction is represented in Fig. 3. The only differences between the belt shown in this figure and that in the preceding figures are, first, the pockets 0 are dispensed with; second, the two plies of each tongue areso proportioned as to form a thimble or pocket (which I distinguish by the reference letter C) of the dimensions required for the cartridge, and third, these pockets 0 are brought as close together as they would be in the 'Mills cartridge belt having only a single layer of pockets. It will be noted that in this belt as in the other I have two layers of pockets'woven in one with the body of the belt, and that the binding warps f, which define the limits of, and close, the pockets of the outer layer on the side next to the belt, are omitted from the fabric of the outer pockets. In this form of belt I gain in number of pockets, since the interval between adjoining pockets of the innerlayer (usually about an eighth of aninch) required for the tongues E, is not necessary in the form of belt shown in Fig.3. But what I gain in that direction I lose in the thickness of the belt as awhole-the belt shown 'in Fig. 3 necessarily being thicker than that in Figs. 1 and 2, where the pockets of the outer layer are partly contained and held in the spaces between the outer portions of the pockets of the inner layer. For this as well as for other reasons which need not be specitied, I prefer on the whole the form of belt shown in Figs. 1 and 2.

I have described my invention as applied to the Mills double ply woven cartridge belt, but manifestly, with such modifications of weaving mechanism as will readily suggest themselves to the skilled workman, it may be applied to a single ply woven belt, or to a woven belt, whether single ply or multiply, in which the pockets extend the full width, instead of only part of the width, of the belt.

What I claim herein as new and of my own invention is- 1. A woven cartridge belt, having two layers of pockets or thimbles woven in one therewith, the pockets of the outer layer alternating with those of the layer next to the body of the belt, and being carried by tongues'extending outwardly between the pockets of the latter layer, as and for the purposes hereinbefore set forth.

2. A woven cartridge belt having two layers of pockets or thimbles woven in one therewith, the pockets of the outer layer being carried by and formed in one with tongues projecting outwardly between the pockets of the inner layer and consisting each of two plies or thicknesses of fabric, jointed at their outer extremities by auxiliary binding warps which are omitted from thefabric of the outerpock- ?ts, as and for the purposes hereinbefore set orth.

3. A woven cartridge belt having two layers of pockets or thimbles woven in one therewith, the pockets of the outerlayer being completed by binding warps which enter into the fabric of the belt but are omitted from the fabric of which the bodyof the outer pockets is composed, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
